Authorites said as part of the investigation, troopers arranged four cocaine transactions from Serna, also known as Luis Borja, between June 3 and June 19. In those transactions, troopers allegedly purchased more than 140 grams of cocaine from Serna.

Only July 28, troopers arranged the purchase of another 250 grams of cocaine from Serna, according to authorities. It was then that Serna was taken into custody and a search warrant was executed at his Parsons Street apartment in Brighton.

The district attorney's office said troopers seized an additional 25 grams of cocaine at the apartment, more than $8-thousand in cash, a digital scale, two cell phones, and notes allegedly related to drug transactions.
